Abstract

A DC/DC converter for driving a load is disclosed. The converter comprises an inductor, a switch having a first terminal, a second terminal and a control terminal, a capacitor, and a rectifying device. The switch and the inductor in series are coupled between a first common point and a second point, and the first terminal of the switch is coupled to a first end of the inductor. A first end of the capacitor is coupled to a first end of the load, and a second of the capacitor and a second end of the load are coupled to the first common point and the second common point respectively. The capacitor provides an output voltage with the first end thereof. One end of the rectifying device is coupled to the first end of the inductor, and the other end is coupled to the first end of the capacitor. The switch is turned ON/OFF according to a control signal.
